Grasses, including rice and other cereals, are a prominent plant group that shows great potential as a source of biomass, in the form of leaves and stems, for biorefining of biofuels and bio-chemicals. Grass species are especially desirable because of their superior productivity and processability compared to other plant types. It is therefore becoming increasingly important to deepen our understanding of the biogenesis, structure and functions of grass cell walls, so-called “lignocellulose,” which makes up the majority of biomass. This project aims to elucidate the molecular mechanisms underlying unique features of grass cell wall formation and seek new strategies to manipulate grass lignocellulose for biorefinery applications. In particular, we will focus on fluorescence imaging analysis of rice cell wall biogenesis and development and characterization of new rice transgenic lines in which lignocellulose composition, structure and/or degree of polymer cross-linking are altered to improve efficiency of biomass conversion to sustainable fuels and chemicals.
